Passing data in Trello OAuth process

Hello!

I am trying to pass data throughout the Trello OAuth process using the REST API, but am getting stuck when the token returns in the redirect url. I can see that the token is returned as a fragment with no other url parameters (a state parameter is where I am storing the data) returned. Is it possible to pass data throughout the the OAuth process using the Trello REST API?

Thank you,

Jody
